A foam dispensing article is provided which includes a reservoir for receiving a liquid product and an operating unit for dispensing foam as an air-liquid mixture. The unit includes an air pump, a liquid pump concentrically surrounded at least partially by the air pump, an operating component positioned above the pumps containing a foam forming screen device, and a spring system. The spring system functions to return pistons of the air and liquid pumps to an unactivated position and includes an inner spring positioned internally concentric to the air piston. The improvement of the present invention is characterized in the spring device having a return force greater than 4 lbs. (17.8 N). In one embodiment, the spring device includes both an outer spring conically tapered and surrounding an inner spring. The outer spring provides the required force in excess of 4 lbs. (17.8 N). Less liquid drip and piston stickage is achieved with the improvement to the spring system.

Foam dispensing article

A dual-chambered dispenser is provided including a pair of elongated hollow tubes containing separate flowable material streams, a manifold for directing the flow through separate chambers, a cap fitting over dispensing openings of the manifold and a metering valve located within the manifold downstream from the dispensing openings. The valve is present to adjust differences in flow rates between the two material streams. In a preferred embodiment, the tubes are juxtaposed along their respective flat outer walls which may include a series of ribs/depressions allowing for coupling of the tubes and strengthening the flat walls against collapse relative to other wall areas of the tubes. Advantageously the valve is a duckbill type and the tubes taper in a pear shape, the broader portion being near the open end of the tubes.

Dual chamber dispenser

A multi-cavity dispensing container is provided for the co-extrusion of at least two flowable materials. The container includes a refill cartridge and a reusable base. The cartridge contains a pair of separate parallel cylinders within which are carried the flowable materials. At a lower end of each cylinder is a piston head. The lower surface of the piston head is configured as a hollow recess. The reusable base is formed with a pair of separate parallel piston support posts. These posts are characterized by a central hub surrounded with at least two outwardly projecting arms. Tops of the posts can readily engage within the recesses of the piston heads. Consequently the refill cartridge and reusable base can be readily engaged and disengaged from one another.

Dispensing container with telescopically arranged disposable refill

A dispensing package is provided with a container and a cap. The cap includes a mechanism to fittingly engage across an open end of the container, a top portion defined by a deck, a skirt wall surrounding the deck, at least one dispensing orifice formed in the deck, a locking aperture with a wide and a narrow area preferably in a T-shape, a lid hingedly attached to the deck, a flexible post projecting downwardly from the lid, and a release mechanism along the skirt. The flexible post has an enlarged section at an end thereof which can lockingly engage underneath landings that define wide and narrow areas of the locking aperture. A flexible area along the skirt can be pushed inward against the enlarged section of the post to dislodge same from underneath the landings thereby opening the lid.

Child-resistant closure

A toothbrush having a head which moves in an arc about the longitudinal axis of the brush in a spiral track. The brush comprises bristles, a bristle base from which the bristles extend, a panel in which the bristle base slides, a head base and a handle. The panel is attached to the head base by a hinge. The panel is curved and includes an elongated aperture which forms the track for the bristle base.

Toothbrush with movable head

A dental mouthwash product is provided that includes a dispensing container with at least two discreet compartments. In a first of the compartments is a liquid component containing hydrogen peroxide. In a second of the compartments is a liquid component containing sodium bicarbonate. The hydrogen peroxide-containing compartment has an outer wall formed completely of opaque material. The compartment containing the sodium bicarbonate has an outer wall of a material whose clarity is sufficient to view the liquid level therewithin. A closure mechanism is sealingly attached to an upper end of the dispensing container. A structure for inhibiting gurgling of the liquid that can occur upon dispensing is provided in the form of either a vent pipe, a divider wall or a U-shaped divider wall. Additionally, there is provided a child-proof mechanism in the form of a release-button controlling opening of a sealing cover on the closure mechanism.

Combined bottle and cap

A disposable multi-cavity refill cartridge, for use with a reusable base and a reusable dispensing head for the simultaneous coextension of at least two flowable materials. The disposable refill cartridge has two hollow and separate parallel inner cylinders for each containing a flowable material. The inner cylinders have a first generally open top end which can be temporarily sealed until the refill cartridge is combined with a reusable dispensing head. The second or bottom end of the refill cylinders telescopically and slidingly accommodate parallel piston heads which are compressibly engageable with piston rods of a reusable base. The piston heads ride sealingly along the interior walls of the inner refill cylinders and when compressed by the piston rods, they force the flowable material to flow out of the refill cylinders and through the outlet means of the dispensing head. Once the flowable materials have been expended, the refill cartridge can be discarded and a new one can be used in conjunction with the reusable base and dispensing head.

Multi-cavity dispensing refill cartridge

A dispensing container is provided for delivery of viscous flowable materials such as toothpaste. The container includes a cylindrical upper body for containing the viscous flowable material and is fitted with an orifice for allowing egress thereof. At a lower end of this body is fitted a piston sealingly slidable within the upper body. The piston is formed from a diaphragm and a skirt of circumferentially concave form surrounding the diaphragm and sealingly slideable against an inner wall of the upper body. Within the piston is a cavity downwardly open. A cylindrical lower body is received telescopically within the cylindrical upper body. A boss portion is formed on top of the lower body and extends into the piston cavity to establish a snug, frictional fit. When the container is exhausted of viscous flowable material, the upper body can be discarded and a refill of similar construction can be mounted on the reusable cylindrical lower body.

Refillable pump dispensing container

A multi-cavity dispensing refill cartridge to be used with a reusable base. The refill cartridge has two hollow, separate parallel cylinders for containing flowable material. The cylinders have a first generally closed end and a second end which accommodates piston heads. The piston heads are compressably engageable with piston rods of the reusable base. Relative compression of the piston heads and cylinders cause flowable material to flow toward the first end of the cylinders and towards the outlet in the closed end. The outlet include means for causing the flowable materials to flow toward each other at the outlet opening. The refill cartridge is provides with means for selectively, engaging the reusable base.

Disclosed is a package for at least two substances which can be dispensed simultaneously. The package comprises a closure system comprising an inclined crown portion, at least two pouring spouts extending upwardly from the upper surface of the crown and a cover for securement to the crown portion, the cover being provided with depending plugs to close the closure. The inclined crown and the positioning of the spouts visually directs the user of the package to dispense the liquid so that premature mixing is avoided.

Disclosed is a packaged effervescible composition which generates fresh effervescence at the time of use. The composition comprises a first liquid component including hydrogen peroxide as a functional ingredient and a second liquid component including sodium bicarbonate as a functional ingredient. The package comprises a container for the components and a closure system comprising an inclined crown portion, at least two pouring spouts extending upwardly from the upper surface of the crown and a cover for securement to the crown portion, the cover being provided with depending plugs to close the closure. Preferably each pouring spout is provided with a vent opening which allows smaller through openings in the spouts. The through openings can thus be positioned closer together on the crown. This gives the advantage that the package can be used dispensing liquids into a small container such as a mouthwash cup with controlled pouring.

Package effervescible composition

A dispensing device is provided including a container having a neck, a fitment mounted on the container having an elongated socket for receiving a roller therewithin and a valve member slidably mounted on the neck and communicating with an inner surface of the elongated socket. The valve member includes a transverse wall with a switch rib jutting outward from an upper surface thereof and projecting through a window formed on the wall of the fitment. A pair of slots flank the switch rib and partially traverse across the upper surface thereof and completely across a skirt projecting downwardly from the upper surface. Additionally, there may be a cutout area located between the slots. Both the slots and cutout area provide flexibility to the switch rib. Fluid communication between the container and fitment is achieved when a cap covering the fitment is removed. During removal, a projection on an inner surface of the cap catches the switch rib thereby moving the valve member upward and then through flexing of the switch rib disengaging same.
